EDWIN W. WEBB' AND CHARLES s. viuuxroia, 'or CHICAGO, ILLINOIS, AssIeNons 'ro STANDARD CAB TRUCK' COMPANY, OF CHICAGO, ILLINOIS, A CQRBORATION 0F NEW JERSEY.

To all' `whom it may concern.'

Be ity known that We, EDWIN W. WEBB and (Timmins S. WAI/ron, citizens of the United' States, residing at Chicago, f'in the countyof Cookland State of Illinois, have invented certain new anduseful Improvements in\Cai`.'-'l`rucks; aiulwe do hereby declaire the following to. be a` full, clean-end exact description of the invention, such as will yenable others skilledin the art to which it'apl'iertains to make and use the same.

Our invention.relates to improvements In car trucks and particularly to six-wheeled equalized car trucks. To the above end, generally Stated, the invention consists of -the novel devices and ,combinations of devices hereinafter described and defined in the parts diagrammatically4 illustrated by means of broken lines; I `1g.,2 a fragmentary plan 'viewof the same; i

are cast integral with the side fra-me 1 and the lower Sections but rigidlyse v said-upper sections by nut-equipped boltsi. The lower extremities of' each pair of pedestals ft yare rigidly conneeted by=a tie bar t'r. These tie bars 6 are detachably secured to the-pedestals 4 by nut- 60 equipped bolts 7F and the ends thereof are bent upward and engage the oiitjefr faces of the pedestals to prevent lateral separation thereof. Charting plates i8 extend substan tially the full length-pf the pedestals 4` and '65 cover the joints between the'sections thereof.

A bolster opening 9` is'formed in the si e x -frame l over each spring-seat 'andthe bottoms ofv saidspring-seats form thebotto'ms of the bolster o iemngs. Over ea'clipair of 70 'pedestals el, ormedlin the a horizontally elongated opening,A :10,the

The car truck Wheels ainLtheir axles are indicated by the numeral 11 and vthejournal 75 boxes therefor are indicated as :entireties by the in lmeral 12, with the exception of rectangulaibearing seats 13 formed infthe `tops thereof.v The ,iournal lioxesll may betrof` ed between the 80 any .desired form, are mou pedestals l and have, on t toiuary pedestal guides. f The' side frames 1 are' rigidly connec' by tfwcii'iaiis ol. angle tie` bars' 14, haviner@ r sides, the custheir `horizoi .tal flaniges'turned toward eac U85 other and 'the ends t iereot'. rest on brackets-,r 15' 'o which they, are rigidly secured :by

The upper sections o' the pedestals l llieibolster for the improved car truck 1s 95 of the double type of cast steel and, as shown, is made up of a centerbeam 16, outer beams 1T and tie eye-beams 18. The bolster beams .1T are located directly, one over, each 'pair oi tie bars 14: and their ends are in- 100 serted lthrough the bolster openings 9 and have formed on their under faces roller contours` l5). which rest on lateral inotion rollers 20. These rollers 20, in turn, are mounted in roller contours '21 forl'ned in roller' bases 105 seated 'on the bottoms of the bolster openitsnmier the :s

Alower center bearing 23 is cast integral with the center beam 16.

While the bolster shown is made u of several rigidly connected by lts and rivets, it is, of course, understood that the sememay be 'cest as an entirety. Side plltarerivetedtothe tie beams 18 inf center beam '16 and prevent my! 'of the car. i Ply flllol'llmed on each journal en lever 25 having on side a fulcrum lug 26 mounted in bearing seat 18 of the res nal box 12.' equalizing evers 25 extend transversely of the journal boxes 12 are located within the side frames 1 and have in each of their ends an elongated ver!V ticslly extended aperture 27. A 'elding abutment 28 is interposed between t e outer end of each outer equelizing lever 25 in the side frame 1. v These abutme as shown, are in the form of coiled sprl 28, seated on sprin fbases -29 and exten in the pockets 2. he spring-bases 29 have on their under sides dlametrically opposite fulcrum lugs 30 seated in notches 31 formed `in the upper edges of the respective ulcrum levers 25. The fulcrum u 30 support the spring bases29 abovevt e equalizmg levers 25 and thereby permit the required oscillatory-movement of said levers. At the centers of the ring- 2 9, 4are depending lugs 82, whi extend er IVBIS 25. and said base P hasinpositionthereon. .y 1

Spring-seat bars 23 are horizontally .sus-A pended under the springfseats 3' by flat links 34 from the inner endsof they outer equalizing levers 25- and the endsifof the inner equalizing levers v2.5. Fulcrum lugs 35, in the form of keys, are extended transversely through the links 34 at the ends thereof. The upper fulcrum lugs 35 are seated in notches 36, formed in the upper surfaces of the equalizing levers -25, and

support the links therefrom and 'the lower' fu crum lugs 35k are seated in notches 37, formed in the undery sides of the springseat bars 33, and support said spring-seat bars thereon. The links 34 are loose y tended through the apertures 27 to permit the required flexibility of the levers 25, spring-seat bars 33 and links 34. Four 've jour -izing levers, links and bolster.

coiled springs 38 are seated on each springseat bar 33 and extend in the overlying -`spring-pocket 3.

Brake-hangers 39 are secured to the inner sides of the side frames 1 by rivets. By reference to Fig. 4, it will be noted that the upper members of the pedestals 4 and the upper ends of the chafing plates l8 are notched or out away to afford clearance for the equalizing levers 25. In assembling the improved car truck, the openings 10 in the side frames 1 `make it extremely simple and easy to position the outer'equalizing levers.,

From the above description, it is evident that the load of the car is directlyon the double ..bolster and it, in turn, bears directly on the side frames through the lateral motion rollers. The weight on the side frames '1s applied directly over the several oups of springs 38, which carri said side rames from the journal boxes t rough the ualspring-seat ars. The spring-abutments 28 compensate for the movement of the equalizing bars on the journalboxes. By the construction and arrangement of parts, just referred to, each wheel is allowed to move vertically, inde-- pendent of the others thereof. The compactness of the above described invention 1s such that an extra air of respeci wheels is added, without increasmfthe' length of the truck 'over a four-.w eeled truck, thereby the capacit of the truck wit no additional weight ona given length of roadbed.
